I would say that using the 'default-information originate' command
instead of redistributing mutually between the three protocols would not
get you the points. Any type of default route should be the last option
unless it is specifically called for in the lab.
Otherwise, why redistribute at all? Just inject a default route in all
of the protocols you are running that will lead back to a central
router...

OK. So I want to make sure I drive this point into my leaking bucket of
a brain!
If I'm doing redistribution on the SAME ROUTER, the routes wont
redistribute the 2nd time regardless of the IGP.
That being said, I guess the way I did it was acceptable. I did a
'default-information originate' on R3 into the RIP domain. I didn't set
a default route, just injected one. Of course I could ping end to end
now, but wasn't sure it that was the answer cause the lab specifically
asked me to inject EIGRP to RIP... As if that would get the OSPF domain
routes there....

Subject: RE: question on EIGRP redistribution
Hi Andrew,
That is a general redistribution problem. When redistributing IN THE
SAME
ROUTER:
OSPF -> EIGRP -> RIP , the OSPF routes will not get into RIP.
Replace those protocols by any other protocol, the rule still applies.
If you want OSPF routes into RIP, you need to distribute OSPF -> RIP
directly.
A different case is R1 running OSPF and EIGRP, and R2 running EIGRP and
RIP. In that case, if in R1 you redistribute OSPF into EIGRP, and in R2
EIGRP -> RIP, then RIP will get OSPF routes. But not if all
redistributions are done in the same box.
Cheers,
Ato.

Subject: Re: question on EIGRP redistribution
I'm having a problem getting EIGRP to redistribute routes into RIP and
wondering if anyone else has ever seen this or could give me some help
figuring it out.
Here's the deal, I have a router (R3) on MP frame relay interface
getting OSPF routes redistributed into EIGRP.
On this router, the EIGRP topology table lists the redistributed OSPF
routes as 0.0.0.0 (originating from self) and they are external routes
(AD170) where FS (4xxxxxxx/0).
I go to R3 EIGRP neighbors and verify that the external OSPF
redistributed routes are being sent to them. That checks out as
expected.
Now I need to redistribute EIGRP into RIP on R3. I do a redistribution
as
follows:
Attempt1:
router rip
Version 2
Redistribute eigrp xxx metric 5
Result 1:
Go to other RIP router and the routes are not there... debug ip rip on
both routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
------
Attempt2:
Router rip
Version 2
Redistribute eigrp xxx route-map eigrptorip
Route-map eigrptorip permit 10
Set metric 5
Result 2:
Go to other RIP router and the routes are not there... debug ip rip on
both routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
-------------------
Attempt 3:
Router rip
Version 2
Redistribute eigrp xxx rout-map eigrptorip
Route-map eigrptorip permit 10
Set metric 5
Route-map eigrptorip permit 20
Match ip route-type external
Set metric 10
Result:
Go to other RIP router and the routes are not there... debug ip rip on
both routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
--------
Using attempt 3 setup, I challenge the router by going to an eigrp
neighbor of R3, setting a Lo0 interface with ip 100.100.100.1/24 and
under this routers eigrp process I redistribute connected. Now, I go to
R3 and do clear IP route * and see internal EIGRP routes redistributed
with metric 5 as expected but this time.... THE NEW EXTERNAL ROUTE GETS
REDISTRIBUTED WITH A METRIC 10!!!!
What I am seeing is on a single an EIGRP router that GETS redistribution
from one IGP and then attempts to redistribute its EIGRP topology table
to another IGP doesn't forward the external routes.
Can someone confirm what I'm seeing? Or am I experiencing some artifact
inherent to the lab.....
Andy
